Dealing with the sys ctrl register should touch only the
relevant bits and not accidently the whole register. On i.MX6,
the sys control register contains bits which shouldn't be reset to
0, e.g. SYS_CTRL[3-0] and IPP_RST_N (SYS_CTRL[23]).
Do this by read/modify/write instead of just a 32bit write.

With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives.
For some obscure reason, the current U-Boot code uses lbaint_t for the
number of blocks to read (a rather optimistic estimation of how RAM
sizes will evolve), but not for the starting address. Trying to access
blocks beyond the 2TiB boundary will simply wrap around and read a
block within the 0..2TiB range.
We now use lbaint_t for block start addresses, too. This required
changes to all block drivers as the signature of block_read(),
block_write() and block_erase() in block_dev_desc_t changed.

Fix two issues with the calculation of pre_div and post_div:
1. pre_div: While the calculation of pre_div looks correct, to set the
CONREG[15-12] bits pre_div needs to be decremented by 1:
The i.MX 6Dual/6Quad Applications Processor Reference Manual (IMX6DQRM
Rev. 0, 11/2012) states:
CONREG[15-12]: PRE_DIVIDER
0000 Divide by 1
0001 Divide by 2
0010 Divide by 3
...
1101 Divide by 14
1110 Divide by 15
1111 Divide by 16
I.e. if we want to divide by 2, we have to write 1 to CONREG[15-12].
2. In case the post divider becomes necessary, pre_div will be divided by
16. So set pre_div to 16, too. And not 15.
Both issues above are tested using the following examples:
clk_src = 60000000 (60MHz, default i.MX6 ECSPI clock)
a) max_hz == 23000000 (23MHz, max i.MX6 ECSPI read clock)
-> pre_div = 3 (divide by 3 => CONREG[15-12] == 2)
-> post_div = 0 (divide by 1 => CONREG[11- 8] == 0)
=> 60MHz / 3 = 20MHz SPI clock
b) max_hz == 2000000 (2MHz)
-> pre_div = 16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 1 (divide by 2 => CONREG[11- 8] == 1)
=> 60MHz / 32 = 1.875MHz SPI clock
c) max_hz == 1000000 (1MHz)
-> pre_div = 16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 2 (divide by 4 => CONREG[11- 8] == 2)
=> 60MHz / 64 = 937.5kHz SPI clock
d) max_hz == 500000 (500kHz)
-> pre_div = 16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 3 (divide by 8 => CONREG[11- 8] == 3)
=> 60MHz / 128 = 468.75kHz SPI clock

Updated the spi_flash framework to handle all sizes of flashes
using bank/extd addr reg facility
The current implementation in spi_flash supports 3-byte address mode
due to this up to 16Mbytes amount of flash is able to access for those
flashes which has an actual size of > 16MB.
As most of the flashes introduces a bank/extd address registers
for accessing the flashes in 16Mbytes of banks if the flash size
is > 16Mbytes, this new scheme will add the bank selection feature
for performing write/erase operations on all flashes.

Read the flash bank addr register to get the state of bank in
a perticular flash. and also bank write happens only when there is
a change in bank selection from user.
bank read only valid for flashes which has > 16Mbytes those are
opearted in 3-byte addr mode, each bank occupies 16Mytes.
Suppose if the flash has 64Mbytes size consists of 4 banks like
bank0, bank1, bank2 and bank3.

Bank/Extended addr commands are specific to particular
flash vendor so discover them based on the idocode0.
Assign the discovered bank commands to spi_flash members
so-that the bank read/write will use their specific operations.

This patch provides support to program a flash bank address
register.
extended/bank address register contains an information to access
the 4th byte addressing in 3-byte address mode.
reff' the spec for more details about bank addr register
in Page-63, Table 8.16
